Designed in the USA, with a lifetime limited warranty, it’s recognized as the best and most accurate of the combination diamond and moissanite testers on the market. With a unique angled ergonomic shape and rubberized paint, it comfortably and securely fits in your hand.

The durable probe tip is spring-loaded to protect it from accidental damage. A white LED lights up the stone being tested, and if touching a diamond, the entire tip area glows green, blue for moissanite, or red if the setting/metal is accidentally touched. A corresponding LED bar graph and specific audible beep tone also indicate test results for the ultimate in fraud protection.
